Sentinel-3 OLCI: Daily Coastal Water Reflectance

Daily reprojected Level 2P remote sensing reflectance data from the Sentinel-3 OLCI instrument, processed by CSIRO for the eReefs Phase 5 project. The product uses the FUB-CSIRO Coastal Water Processor to derive above-water spectral reflectance at a reduced resolution of approximately 1000 meters per pixel. It includes multiple quality flag layers for data control, such as standard Level 1 flags and algorithm-specific out-of-range flags.

Use Cases

• Monitoring coastal water quality trends based on spectral remote sensing reflectance.
• Assessing phytoplankton dynamics and suspended sediments using multi-spectral reflectance data.
• Validating hydrodynamic and biogeochemical models for reef systems with satellite-derived reflectance.
• Applying quality control for satellite ocean color products using the provided flag layers (file_version_quality_control, in_out_OR_combined_flags).

Strengths

• Processed using a peer-reviewed algorithm detailed in a scientific publication (https://doi.org/10.1016/j.rse.2021.112848).
• Includes multiple, documented quality flag layers for rigorous data control.
• Data is regularly updated, with the most recent platform update recorded on 2026-04-28.

Limitations

• Critical metadata is missing from all platform entries, including column names, row count, file size, license, and author.
• The spatial resolution is reduced (approximately 1000m), which may limit analysis for fine-scale coastal features.
• The dataset's provenance and specific geographic coverage are not explicitly stated in the provided metadata.

Provenance
